refactor: cleanup configs, unify session handling

- flake.nix:
  - Close braces formatting for `allowUnfree`
  - Remove per-user `custom.sessionType` modules
- home-manager:
  - home.nix: remove unused apps (bambu-studio, hydralauncher, keymapp, etc.)
    - drop librespot service
    - add waydroid
    - fix kitty font_family spacing
  - gnome: add gnome-tweaks and appindicator extension
  - vim: update nixvim module import path
  - zsh: drop sessionType option and conditional aliases
    - hardcode wl-copy/wl-paste as pbcopy/pbpaste
- hyprland: style fixes in braces, spacing, keybind comments
- hosts/Nixstation:
  - remove gnome-session and redundant tweaks
  - remove env vars NIXOS_HOST / NIXOS_DE
  - enable virtualization (libvirtd, spiceUSBRedirection, vmware.host=false)
- hardware-configuration: reformat fileSystems definitions
- common/nvidia:
  - remove explicit kernelPackages override
  - ensure xserver.enable=true and GNOME/GDM config intact
- users/thiago: reorder and regroup extraGroups list
